Exercise
1. Give some examples of malicious software that is capable of damaging hardware.
As an example, a malicious program can move the read/write head of a magnetic disk back and
forth repeatedly every time the disk is not used by legitimate software, thereby wearing out the
disk’s high precision mechanism. Repeated “treatment” of this kind may shorten the life of the
disk considerably.
The popular flash memories can be damaged in the same way.
2. What Is Meant by Malware?
A is software used or created to disrupt computer operation, gather sensitive information, or gain
access to private computer systems.
It can appear in the form of code, scripts, active content, and other software.
Malware' is a general term used to refer to a variety of forms of hostile, intrusive, or annoying
software
3. What Are the Damages of Malware?
Data Loss: Many viruses and Trojans will attempt to delete files or wipe hard drives when
activated, but even if you catch the infection early, you may have to delete infected files.
Account Theft: Many types of malware include keylogger functions, designed to steal accounts
and passwords from their targets. This can give the malware author access to any of the user's
online accounts, including email servers from which the hacker can launch new attacks.
Financial Losses: If a hacker gains access to a credit card or bank account via a keylogger, he
can then use that information to run up charges or drain the account. Given the popularity of
online banking and bill payment services, a hacker who manages to secrete a keylogger on a
user's system for a full month may gain access to the user's entire financial portfolio, allowing
him to do as much damage as possible in a single attack.
Exercise
1. Is it possible to scan files for new, as yet unknown, viruses?
Yes, to some extent, because many new viruses are created from virus kits and are therefore
modified versions of existing viruses, so their codes are similar. Old versions of Norton anti-
virus software for the Macintosh, made by Symantec, promised to do just that.
2. What Is Anti-Malware Program?
Anti-Malware Program: Anti-Malware program is used to prevent, detect, and remove computer
viruses, worms, trojan horses and any other type of malware.
Examples of Anti-Malware program:
